The Monocat was not a scaled hull of a catamaran, but rather a Marblehead hull designed after one hull of a catamaran.
The boat was designed for minimum wetted surface and hullform resistance, which is why the idea came from a Cat.

The hull ended up with anti-dive rails along the sides of the bow.. Which should tell you it's major downfall in inconsistencies when competing at high level events.

It should still be a very fast boat, but any builder should be weary of it's downwind performace with a super-high-aspect ratio rig.

Hi all I was just reading thru both sets of rules I have and no where can I find a requirement for a drum winch it does say the the jib the main and the rudder can be controlled by radio which I take to mean you can have more than two channels
of radio after all as been pointed out this is a development class also prior to ISAF 1996 there was a requirement that keel weight be behind the keel there is a name for this which I can not remember I have 2 questions
[1] what is an alternate rig

[2] what is a swing rig

and thirdly why would a Ketch not be totally legal if built to those rules Casey

Other than simplicity, does a swing rig offer any advantages to separated main and jib?

They tend to be quicker to change rigs. On my Viper, I use a swing for the A, then conventional for B and C. Will do the same for my Pixel. The swing rig works really well in the light air, but tends to go bow down sooner in heavy air.

I'll try to make the most sense of that that I can..

On a Marblehead class boat you are permitted to use more than 2 channels, but it is not advisable. Why, is a higher-level conversation
Typically the Mainsail and Jib are controlled on the same Drum winch, and a single channel.The second channel is used for the rudder.
For drum winch setups, see this document. Scroll to the drum winch section.

I took some pictures while at a recent RM rankings race last weekend Graham Bantock won the day with his Prime Number with Peter Stollery and his father Roger placing second and third with there own design Crazy Tubes.
An interesting array of marbleheads there including Rok's, Paradox and some Starkers 3's including mine.
